  • Wireless local loop antenna
    Patent number: 8121533
    Abstract: A wireless local loop system is provided that includes a wireless base station that communicates with a subscriber station via a wireless link. The wireless link can carry a voice service, such as telephone calls, or a data service, such as internet browsing. The subscriber station includes a steerable antenna. A presently preferred steerable antenna for use with the subscriber station includes a driven element mounted on a base plane that is surrounded by a plurality of parasitic elements also mounted to the base plane. The parasitic elements can be optionally grounded or floated in order to reflect the wireless link towards the driven element. The antenna can be oriented in a desired direction during the transception of a voice or data service. A method of transceiving between a wireless local loop subscriber station and a wireless local loop base station is also provided.
